Just relax and enjoy.
Only the first 10m are a bit awkward, after that it just feels normal seeing eachother naked.
Even afterwards, nothing will change. They remain the same people, you've just seen each other naked.
And nowadays, naked is not that much less clothing that some of those small bikinis. Often seeing eachother naked is less erotic than seeing one another in a sexy dress or bikini.
